Title: Maintenance apparatus for maintaining the alley surface of bowling alleys
Inventor: GAST XAVER
IPC: A63D5/10
Filed: 1984-02-09
Abstract: For maintaining the alley surface (15) of bowling alleys, a trolley (1) is guided in the lateral channels (13) and bears a tool trolley (8) which is guided reciprocally transversely to the direction of travel of the trolley (1) and a tool motor (10) with two tool supports (54) and (55), driven thereby, for interchangeably attached maintenance elements (56) such as annular brushes. The trolley guide (7) is individually adjustable by means of cranks (64) relative to the alley surface (15). The driving motor (9) drives, via bevel gear drives (20) and a drive shaft (21), the running wheel (4) which is fixedly mounted on the trolley frame (2) in the direction of travel. The axles (23) of the other running wheels (3, 5 and 6) are mounted via vertical bolts (24) on the trolley frame (2) so as to be pivotably adjustable and are laterally guided by means of an angled steering lever (25) and a contact roller (27) in the upper region of the channel (13). The reversible drive, which is to be controlled by end switches, thus permits fully automatic maintenance of the alley surface (15) by means of the maintenance elements (56), to which can also be added special maintenance or polishing agents. <IMAGE>
Patent DE-3410313-A1 (DE)
Title: Pipe or cigarette holder or cigar holder
Inventor: SCHMUDDE HERMANN
IPC: A24F7/02
Filed: 1984-03-21
Abstract: In mouthpieces of pipes or cigar holders or cigarette holders, it was hitherto possible to observe a more or less intense discoloration and/or taste impairment when the mouthpieces had been exposed to the effect of light for at least a time. The cause of the discoloration or taste impairment is the salts which are bound in the material of the mouthpieces and crystallise out under the effect of light and are deposited on the surface of the mouthpiece. In order to avoid the crystallising out, the invention now provides a film-like coating 3. This consists of a quick-drying, light- reflecting or opaque and food-compatible and non-toxic liquid plastic. After curing, this plastic forms an elastic protective skin 3 which closely surrounds the mouthpiece 1 and can be pulled off in large pieces when the mouthpiece 1 is used. <IMAGE>
Patent DE-3410940-A1 (DE)
Title: Rudder with blades and method of manufacturing it
Inventor: MORI MASAHIKO
IPC: B63H25/38
Filed: 1984-03-24
Abstract: An energy-saving rudder with additional blades is described. The additional blades extend away from a conventional rudder so that the rotational energy of the propeller stream which strikes against the additional blades can be recovered and converted into a propulsion thrust. Likewise, a method of manufacturing a rudder with blades is described. The marginal section (profile rear edge, front edge and tip section) of each additional blade and its extension section are manufactured separately in a casting process, and the top and bottom blade coverings are firmly welded to the frame, which is prepared by the assembly of the marginal section and the extension section of each additional blade. The additional blades can be manufactured and positioned with a high degree of accuracy.
Patent DE-3418828-A1 (DE)
Title: Automatic gyro-controlled multi-stage transmission for road vehicles
Inventor: SORO LADISLAUS
IPC: F16H33/10
Filed: 1984-05-21
Abstract: The transmission makes possible a linear automatic shift from the first speed to the higher speeds (gears) and vice versa as a function of the change in the loading of the vehicle. The transmission is composed of two main sub-assemblies:   1. Two (or more) asymmetric gyro pairs by means of which the automatic control is performed. 2. Two (or more) one-way clutches, which serve to couple and decouple the particular disc gearwheel pairs. (The number of gyro pairs and one-way clutches is dependent on the number of speed stages.)   When starting, the vehicle is driven only by the first stage (greatest reduction) (gear wheels 1a and 11). When a somewhat higher speed has been reached, the task of driving is taken over by the first gyro pair (4a) (4a) and the torque is transmitted via gear wheels (6) and (12) and the one-way clutch (16). At a still higher speed, the second gyro pair (7a) (7a) is operative and the torque is transmitted directly, exclusively by the gyro pairs, to the output shaft (18). In the direct gear, the disc gear-wheels of the lower speed stages (11, 12, 13) are decoupled by the one-way clutches (15) (16). <IMAGE>

Title: Chain mechanism (dérailleur)
Inventor: WESTBROCK BERNHARD
IPC: F16H9/06
Filed: 1984-05-25
Abstract: Chain mechanism with an input shaft and an output shaft, on which sprocket wheels are arranged and enveloped by a link chain, one strand of which is provided with a spring-loaded and automatic tensioning device. The link chain can be moved from one sprocket wheel to at least one other sprocket wheel on the same shaft in order to change the transmission ratio of the mechanism. A chain lift-off device (20) is guided approximately in an arc (17) and with a clearance around the largest wheel (2 or 7) on a shaft (1 or 6) and, within the angle of wrap, lies against the inside of the chain (8-9). This makes it possible for the chain (8-9) to be raised from the sprocket wheel and held raised, the chain lift-off device (with the raised chain) on the one hand and the shaft with the sprocket wheels on the other hand being displaceable relative to one another in the axial direction of the shafts (1 or 6). <IMAGE>

Title: Method for reliable transmission of information between data stations
Inventor: PFEFFER ROLF DIPL ING
IPC: H04L1/18
Filed: 1984-06-22
Abstract: The invention relates to a method for reliable transmission of information between data stations in which the receiving station acknowledges reception. If the acknowledgement is absent, the information transmission is repeated, an increase in the reliability of the transmission, particularly in the case of control commands, being achieved by transmitting a predefined number of repetitions within a monitoring time (tv) and by forwarding the transmitted data records to peripheral devices only if the received data record is not a repetition, a record counter (SZ) being entered in each data set which is not transmitted as a repetition (WK = 0). The invention can be used particularly for information transmission in telecontrol systems. <IMAGE>
